Key differences
Supported differences are shown below. Data limitations are labeled separately.
- Data limitation
No geometry is recorded for 2005 Jamis Comet and 2007 Jamis Comet.
- Data limitation
Only 2005 Jamis Comet has enough published drivetrain data for gearing calculations.
- Identity & price
2007 Jamis Comet had an original MSRP $599 lower than 2005 Jamis Comet.
Original MSRP is the published list price when new, not today’s used-bike value.
Gearing comparison
Lower gears help on climbs. Higher gears suit higher speeds.
RPM
RPM = pedal turns per minute.

Uses front tire 700C×23; rear size isn’t listed.
Gearing unavailable for this size.
How it works
Ratio = front teeth ÷ rear teeth. Hub gears also include the hub’s internal ratio. A 400% range means the highest ratio is four times the lowest.
Speeds are estimates from tire size and pedal cadence. Actual speeds vary.
